| Abstract: | Technical term automatic extraction is one of the important topics in Chinese information processing.It has been widely applied to information retrieval,machine translation,especially in the patent machine translation.In this paper,the research mainly focuses on the recognizing method of the technical term combined the patent machine translation task,proposes a technical term recognition method based on the statistics and rules at the base of the analysis of existed method.It first uses Conditional Random Fields(CRF) model to label and recognize the corpus,then a post-processing step based on rules is used to correct the wrong labeled result.The experiment results show the method is efficient for identifying technical terms,in open test the F-value reaches 84.4%. |
